Clinical Consultation Summary

• Patient self-reports no progressive memory failure; occasional afternoon mental fatigue coincides with high workload and irregular sleep.
• Circadian tracking indicates 82% sleep regularity (avg. 6.8 hrs). Diurnal fasting context recorded (no acute hypoglycaemic interference during testing).
• • Informant pulse (Caregiver AD8 Brief): Score 0/4 (No independent activity disruption observed by family).

Composite Brain Vitality Index 85/100. Stable within Reliable Change Index band (baseline 84 ± 4). Zero statistically significant neurodegenerative drift detected across 6-month interval. Borderline systolic blood pressure and low-normal B12 represent modifiable reversible targets under Lancet 2024 dementia prevention guidelines.

1. Review cardiovascular & metabolic baseline: Fasting blood glucose, HbA1c & lipid profile confirmation.
2. Serum B12 + methylmalonic acid recheck within 4 weeks; consider sublingual replenishment.
3. Lifestyle prescription: Structured zone-2 aerobic activity (target 150 mins/week) to mitigate vascular risk.
4. Follow-up: Continue bi-weekly on-device micro-assessments; re-evaluate RCI trajectory in 3 months.
